java.lang.RuntimeException: Parcelable angetroffen IOException Schreiben Serializable-Objekt kann nicht finden, was falsch ist

Question

Ich bin mir nicht sicher, was mit meinem Code falsch ist. Ich habe sichergestellt, dass alle Objekte Serializable implementieren. Ich habe mir schon andere Fragen angeschaut, kann aber immer noch keine Lösung finden. Kann mir jemand helfen, herauszufinden, was nicht stimmt? Danke

Hier ist, was er sagt, in der logcat

ich wirklich hier bin stecken. Ich habe immer und immer wieder überprüft, dass alle Objekte Serializable implementieren, aber ich bin mir immer noch nicht sicher, was das Problem ist. Vielen Dank!

Answer 1

Bei diesem Verfahren

public void onClick(View view) { 
    Intent intent = new Intent(appContext, AdminControls.class); 
    intent.putExtra("adminInterface", adminInterface); 
    appContext.startActivity(intent); 
} 

Sie passieren benutzerdefinierte Objekt mit diesem er versuchte ich

public void onClick(View view) { 
    Bundle bundle = new Bundle(); 
    bundle.putSerializable("adminInterface", adminInterface); 
    Intent intent = new Intent(appContext, AdminControls.class); 
    intent.putExtras(bundle); 
    appContext.startActivity(intent); 
}
